Systems and Methods for Phase Identification Using Relative Phase Angle Measurements

4. The system of claim 1, wherein the synchronization message is transmitted using a wireless communication protocol.

5. The system of claim 4, wherein the wireless communication protocol is an RF communication protocol.

6. The system of claim 1, wherein the one or more node devices are selected from a group consisting of electronic metering devices, sensors, and distribution automation devices.

7. The system of claim 1, wherein the one or more electronic processors of the gateway device are further configured to transmit the determined phase to the first node.

9. The method of claim 8, wherein the method is performed by a central computing device.

10. The method of claim 8, wherein the method is performed by a plurality of gateway devices in electronic communication with the one or more nodes.

11. The method of claim 8, wherein determining the phase of the first node device comprises determining a relationship of the duration value of the first node device to the durational values received from the at least one node device with a known phase connection, and wherein the phase of the first node device is determined to be one of the same phase, a +120° offset phase, and a −120° offset phase based on the determined relationship.

13. The method of claim 12, wherein the synchronization ID value is associated with the received synchronization message.

15. The method of claim 8, wherein the duration values received from the at least one node device with a known phase connection are determined based on the first synchronization message.

17. The method of claim 16, wherein the synchronization ID value is associated with the received synchronization message.

19. The method of claim 18, wherein the synchronization ID value is associated with the received synchronization message.

20. The method of claim 16, wherein the duration values received from the at least one node device with a known phase connection are determined based on the first synchronization message.
